Overview Tripp Lite's SmartRack SRCABLETRAY safely routes cables across the top of an enclosure. When cabinets are lined in a row, these trays create a dedicated path for cables helping to eliminate cable stress. The SRCABLETRAY organizes cables outside of the SmartRack enclosure. It offers toolless mounting to the top of the rack panel and a grounding stud is provided to allow tie-in to the enclosure and the facility ground.
